MACHINE FOR MAKING SHOE AND UPHOLSTERERS NAILS.

SPECIFICATION forming part of Letters Patent No. 280,458, dated July 3, 1883.

Application filed June 10, 1882. (No model.) Patented in Germany May 16, 1880, No. 13,303.

To all whom, it may concern Be it known that I, RUDoLF EGLI, of Rapperschwyl, .in the Republic of Switzerland, have invented certain new and useful Improvements in Machines for Making Shoe and Upholsterers Nails, of which the following is a specification.

This invention has reference to an improved machine for making shoe and upholsterers nails, of any desired size and shape, froma continuous piece of wire, of proper thickness, that is fed through the machine and acted upon successively by the different mechanisms composing the machine in such a manner that eachrotation of the driving-shaft of the machine produces an entirely-finished nail.

The invention consists, essentially, of a combination of the following instrumentalities: first, a mechanism for taking up and intermittently feeding the wire to the machine; secondly, a cutting mechanism whereby nailblanks of proper size are out off from the wire and the shank of the nail is formed; thirdly, a carrying mechanism which takes hold of the nailblank and conducts it forward to the jaws of the lower die, which is arranged in front of the cutting mechanism, and to which jawsthe nail-blank is delivered; fourthly, a drop-die that is released at the proper moment so as to form the head of the nail while the blank is supported by the lower die; fifthly, an oscillating mechanism for throwing out the finished nail; and, lastly, of suitable power-transmitting mechanisms, whereby the proper motion is imparted to the different working parts of the machine from a common driving-shaft, which mechanisms will be more fully described hereinafter.

In the accompanying drawings, Figure 1 represents a front elevation of my improved machine for making shoe and upholsterers nails. Fig. 2 is a side elevation. Fig. 3 is a plan view, with parts broken away, of the nail-blank-carrying mechanism; Fig. 4 is a planview of the cutting mechanism, drawn on a larger scale, showing also the lower die or anvil and the throwing-out mechanism. Fig. 5 is a vertical transverse section of the machine. Fig. 5 is a detail side view of the spring that actuates the drop-die, together with some other details. Figs. 6 and 6 are a detail front and side elevation of the Wire-feed ing mechanism, Fig. 6" is a top view of Fig.

'6. Figs. 7, 7, and 7 are a detail side View,

an end view, and a top view of the mechanism for holding the wire for the action of the cutting-dies. Figs. 8 and 9 are detail end views of the fixed and movable knives for cutting off the nail-blanks. Figs. 10 and 11 are detail top and side views of the mechanism for carrying the nail-blanks from th e cutting mechanism to the lower die or anvil. Fig. 12 is a detail side view of a nail-blank, the dotted lines indicating the manner in which the blanks are cut from the wire; and Figs. 13, 14, 15, 16, and-17 are perspective views of different shapes of shoe and upholsterers nails, which can be made by my improved machine.

Similar letters of reference indicate corresponding parts.

A in the drawings represents a strong supportingframe of cast-iron or other suitable material, which frame consists of upright side standards, A, transverse connecting-pieces A and a table, B, upon which the cutting and nailblank-carrying mechanisms are supported. At the lower part of the supporting-frame A is arranged, on a supporting-bracket, a fixed spindle for the wire-reel C, from which the wire is fed to the machine. From the reel C the wire is conducted to the intermittentlyactuated wire-feeding mechanism D, which is attached to an upright portion of the frame A, below the table B, and vertically below the cutting-knives.

The wire feeding mechcmis'm. The wirefeeding mechanism D is shown in detail in Fi s. 6 6 and 6" and consists of a su J )ortg i 7 a 11 ing-platc, d, which guides in suitable ways a sliding carriage, d. The lower partof the supporting-plate d is formed with a bracketplate, (1 which is arranged at right angles to the plate, and carries at its lower end a hook- V shaped arm, (1, having a guide-opening corresponding to the cross-section of the wire.

Above the guide-opening of the arm (1" are applied to the bracket plate (Z three wirestraightening rollers, dtwo on one, the third on the other side of the wire. The bearing of the third roller (1 is adjustable by a screw, (P, so as to be set nearer to or farther away from the opposite rollers, whereby they can. be accurately set to the thickness of the wire. The wire is conducted from the straighteningrollers (1* past a fixed retaining-cheek, d, and

an inclined dog, (1 which latter is adj ustably secured to a fulcrumed sleeve shown clearly I in Fig. 6, so that the sharp edge of the dog bites the wire and presses it against the retaining-cheek (1, whereby the receding of the wire is prevented at the moment when the forward-feeding motion is interrupted. The dog d is made adjustable in its fulerumed sleeve, so as to be set, like the straightening rollers, to the thickness of wire used. The wire is then taken up by the feeding mechanism proper, which consists of a serrated jaw, (1 and a steel friction-roller, d, between which the wire is passed in upward direction. The jaw 11 is supported on a bearing,.2, on a lever, (2 that is pivoted to the sliding carriage d, the grooved serrated jaw (6 serving to bite the wire and press it agai ust the steel frictionroller (2". This roller ismade in two pieees,one narrower than the other, so that when the wide piece has become worn it can be reversed with thenarrow part of said. roller. (1 is an ad justing-serew on the lever d", and is for adjusting the jaw (i and forcing the same against the wire when the jaw is worn. The friction roller (Z9, as well as the pivoted lever d", is retained on the sliding carriage d by a cover ing-plate, d", secured by screws (1. The sliding carriage d is adjusted higher or lower in its ways on the supporting-plate (Z by means of a vertical adjusting-screw, d, which turns in a screw-socket, d, and bears on a fixed seat of the main plate (I, so as to exaetlyregulate the distance to which the wire is to be fed forward, according to the size of the nails to be made on the machine. The lever (1 on the sliding carriage d is operated by one end of the lever d, which is fulcrumed to the main frame at d Fig. 1, as shown in dotted lines in said figure. Lever (Z is made in two sec tions rigidly secured to a plate which constitutes a part of the lever, and which is the part fulcrumed to said pivot d. The opposite end of the lever d is operated by a vertical rod, d,which is guided in side bearings, (1 ,011 one of the side standards, A, of the frame A, as shownclearly in Figs. 1 and 2. The lever d abuts against the under side of lever (1 as shown in Fig. 6, and when the rod (1" is depressed,the opposite end oflever d rises,and, acting on leve1'(,serves to move the carriage upward. The rod (1" is moved downward at each revolution of the driving-shaft S by a p rejection or nose, (1, on a ring or eccentric, d which latter is attached by a set-screw, d, to the inner face of a hub or collar on the outer end of the driving-shaft S, as shown in Fig. 1. \Vhen the nosed eccentric d presses downward 011 the rod (1", it forces the lever (1 down, raises the opposite end thereof and presses it against the lever d", so as to force the jaw (l against the wire,which in turn is held in place on its opposite side by the friction-roller d". This motion of the lever (1' also lifts the slid-j ing carriage d, with its lever (1 and feeds the wire forward the distance required by the size of the nail-blank.

anism for cutting the nail-blanks from the wire is shown in Figs. 4, 8, and 9. Before the wire is cut oil by the cuttin -knives it is passed through ahole, b, in the table 113, (shown in Fig. 5,) and then guided iutermediately between the table 18 and the cutting-knives along two stationary guidejaws, c c", the lower jaw, c, of which has a guide-groove in its face, and is adjusted by a set-screw, a, to the proper size of the wire, while the upper jaw, c, is arranged at the opposite side of the wire, andis similarly adjusted by a screw, 0, as shown clearly in detail in Figs. 7, 7, and 7". The upper jaw, 0 is also grooved for guiding and retaining the wire, said grooves being rounded off at the lower part of the jaws, so as to permit the easy introduction of the wire when the machine is started for work. The two guiding and holding jaws c and 0* are supported and adjusted in a step-shaped box, (1, bymeans of suitable screws, as shownin Fig. 7, 7, and 7". The box or easing c", which supports the guiding and holding jaws c e, is secured in the proper position on the table B by suitable setscrews, as shown in Fig. The cutting mechanism proper consists of a fixed knife, o and of a laterally-movable cutting-knife, c, the knives being so formed as to shape the nail-blank as shown in Fig. 12. The movable cutting-knife (2 serves also for the purpose of pressing the shank of the nailblank against a fixed check, (2 that is arranged in front of the fixed cutting-knife c", and locked tightly sidewise of the same to the supporting-plate 0" on the table B by a wedge-shaped lockingpiece, 0, which is securely held in position by pressure-screws c", as shown clearly in liigs. @tand 9. The movable cutting-knife a is se cured in arecess of a sliding carriage, c, which moves in fixed ways a", and is retained there in by a side piece, 0", (shown clearlyin Fig. 8,) while the cutting-knife is tightly secured in the sliding carriage e by a wedge-piece, e, which is retained by pressure'screws c, as shown in Figs. i and The movable cutting-knife c is adjustable in its sliding carriage by means of an adjusting-screw, 0", which serves to adjust said knife after it has been sharpened, and thereby shortened. The fixed cutting-knife a", as well as the cheek against which the wire is pressed during the cutting action, is also adjustable by set-screws c and c", as shown in Fig. 4. The supporting-ways c of the movable cutting-knife, as well as the supportingbox a of the fixed cutting-knife, are screwed down upon the table B by a number of fastening-screws, c". orally by means of the adjusting-screw a which passes through lugs east on the table B. The object is to bring the sides of the knives c and c directly in line with each other, so that they can just pass each other. The movable cutting-knife c" is actuated by an oscillating lever, a, which is pivoted at its lower end to the front part of frame A, and engaged at its upper by a grooved cam, e', of the shaft The lever e acts upon the rear end of the The box 0 is adjusted latsliding carriage (2 at each revolution of the to an upright oscillating rod, f This rod is driving-shaft, said lever being shown in cross section'in Fig. 4 and in side elevation in Fig. l, the lever in Fig. 4 being shown passing through an opening, 6 in carriage e The nail-blank which'is cut off by the cutting mechanism consists of a thicker upper part,

from which thehead of the nail is formed, and of a pointed lower portion, from which the shank is formed, as shown clearly in Fig. 12.

The naiZ-bZank-carrying mechcmism.-The nailblank carrying mechanism F is shown in Figs. 1, 3, 5, 10, and 11, and consists, essentially, of two fulcrumed jaw-levers, f f, which carry the jaws f, that take up the nail-blank, one jaw having a straight face, the other an angularly-grooved face, as shown in Fig. 10. The jaws are retained in grooves of the j aw-' levers by means of retaining wedge-pieces f, that are applied to the dovetailed shanks of the jaws. The jaw-levers f are fulcrumed to the forked support f and provided at their rear ends with oblique slots, to be engaged by the connecting-pins f t of a short lever, j"*", that is fulcrumed intermediately between the actuating-pins f to the forked support f. The outer end of the short lever f 5 is pivoted to the inner end of a fulcrumed lever, F, which serves to operate the entire nail-blankcarr'ying mechanism, Figs. 1 1 and 3. I The forked holder f 3 is rigidly secured to the front end of a guide-rod, f, which is guided in a stuffing-box, f, in a support, f secured rigidly to the table B, as shown in Figs. 5 and 11. The guide-rodf" slides in the stuffing-boxj, the packing material of which serves to retard the motion of the guide-rod to some extent, for the purpose of stopping the carrying mechanism, until the jaw-levers are entirely opened or closed when they arrive at the ends of their movement. The friction upon the guiderod f 6 is regulated by compressing the packing material in the stuffing-box in the usual manner. To the rear end of the connectingrod f 6 is applied, by a fixed connecting-piece,

f, an auxiliary guide-rod,f which slides in a lug on the stuffingbox f said auxiliary rod serving the purpose of preventing the guiderod f from turning upon its axis. The stuff ing-boxj' is further provided at its front and rear ends with stop-screws f, which serve to stop the nail-blank-carrying mechanism F in its forward and backward movements, so as to stop the jaws f exactly at the point where they take the nail-blank from the cutting-knives e e and at a point vertically above the fixed lower die or anvil, G, which is arranged at the front part of the machine. The fulcrum f of the actuating-lever F of the nail-blankcarrying mechanism is supported in lugs f of the side standards, A, of the supportingframe A, as shown in Figs. 1 and 3.

socket, f to which is attached a backwardlyextending rod, f, which is screwed at its front end into the socket f and at its rear end The outer end of the lever F is pivoted toa screwpivoted at its lower end to a fixed pivot-pin, f at the lowerpart of the supporting-frame A, as shown in Figs. 1 and 2, and at its upper end to a link, P", that is pivoted to a slidepiece, j, which is adjustable in a diametrical dovetailed groove in a plate, f at the end of the driving-shaft S. The slide-piecef is adjusted nearer to or farther away from the center of the driving-shaft S by an adjustingscrew, f whereby the motion of the nailblank-carrying mechanism may be made equal to the exact distance of the cutting-knives e e from the lower die, G. The adjusting-screw f regulates the extent of motion of the carrier so as to do its work properly, while the screw-rodf, that connects the oscillating 1everf with the fulcrumed lever F, serves to adjust the mechanismv forward or backward relatively to the knives or to the lower die, so that consequently the proper position as well as the requisite motion is imparted to the nailblank carrier.

The nailforming dies.The dies by which the proper shape is given to the head of the nail are clearly shown in Figs. 1, 4, and 5. They consist of the lower die, G, which is formed of two sections or jaws, g g*, that form a kind of anvil, and the dropdie G. The jaws gg are attached to a base-block, 9, said base-block being adjusted higher or lower by a vertical set-screw, 9 (shown in Fig. 5,) as required by the gradual wearing off of the die. One of the jaws, g, is rigidly held by a set-screw, i, Fig. 4, to the supporting base-block g and to the front upright, A, of the supporting-frame,

while the other jaw, g is made movable and 9 acts upon the outer end of the slide-piece while the spring g acts upon a projecting lug of the same, as shown clearly in Fig. 1. Then the nail-blank carrier F has arrived at the end of its forward motion, it is vertically above the lower jaws, g 9*, as shown in Fig. 1. The jaws of the carrier are then opened and the nail-blank is inserted into the space between the die -sections g 9. For this purpose the movable jaw g is drawn back by its actuating mechanism so as to admit the pointed shank of the nail-blank into the tapering socket formed by grooves in the faces of the jaws g g*. The moment that the blank is delivered to the jaws g 9* the lever g and slide-piece 9 press the movable jaw forward to take hold of the shank of the blank. As soon as the carrier F has delivered the blank to the jaws g 9* it is returned out of the way of the drop-die G, which is then dropped to form the head of the nail. Thedrop-die G is arranged vertically above the lower die, G, at the lower end of a heavy cylinder, 9", which is guided by the upper part of the supporting-frame. die G has at its lower end a recess or indentation of suitable shape, according to the shape to be imparted to the head of the nail. To the middle portion of the drop-cylinder g is keyed a piece, g which passes through it and proj ects both forward and backward, the rear portion being engaged by an eccentric cam, g, on the driving-shaft S. This cam raises the drop cylinder {1", the upper end of which compresses at the same time a strong elliptic or V-shaped spring, 9, that is made of wood, steel, or other suitable material, and is connected to the ceiling or other point of support. The upper end of the spring 9" is connected by adjustable side rods, 9 and clampscrews g' to the upper transverse portion of the supporting-frame, shown in Fig. 1, so as to impart a greater or less tension to the spring g for obtaining lighter or heavier blows of the drop-die, according as smaller or larger nails are to be made in the machine. Two set-screws, q, secure the upright q, to which thesiderods, g, are attached, to the frame. A split screw-collar, 9", is applied to the threaded upper part of the dropcylinder g" by clamp-serews. The collar-y regulates the drop of the die G and strikes an elastic cushion or plate, 9, arranged 011a seat at the top part of the supporting-frame,whereby the injuring of the lower die by the dropdie is prevented in case the latter is dropped without a nail-blank having been delivered to the former. The drop-cylindergisprevented from turning on its axis byaspline, g", which is secured to the upper part of the same below the split collar, said spline being guided in a corresponding groove in the upper part of the frame A, as shown in Fig. 5. The drop-cylinder moves in two guidesleeves, which sleeves are connected by vertical side pieces, 1 held in ways 9*, and secured by suitable adjusting-screws, ((7, to said ways or uprights g, at the front part of the frame. The guidesleeves g may be laterally adjusted by the setscrews a, and also forward or backward by ad justing-screws c so that the exact position of the drop-die relatively to the lowerdicmaybe obtained. To lugs 011 the lower guide-sleeves, g, of the drop-die G is pivoted a socket, 1 that carries an adjustable rod, g, by which the drop-cylinder is supported when the rod g is swung up in vertical position below the forward projecting front end of the piece the rear end of which is engaged by the eccentric cam when lifting the drop-die. The dropdie is retained thereby in raised position whenever any part of the machine has to be adjusted or placed in proper order.

The throwing-out 121cc]: (mi sm .The throwingout mechanism H consists of a lever, 72, which is arranged in an inclined position between the lower die-sections, g g, as shown in Figs. 1, 3, and 5. The lever I1 is adjustably secured by a set screw to the end of a lateral shaft, h, that turns in bearings 71? at the front part of the supporting-frame A. To the outer end of the shaft h is applied a rearwardly-extending The drop- I crank-arm, h, that is connected by a rod, 71;,

with a fulcrumed lever, h the curved rear end of which is acted upon by a cam or wiper, h", on the driving-shaft S, as shown in Figs. land 2. The throwing-out lever h is thrown forward by its actuating mechanism at the mo ment when the lower jaws, g 1* are separated from each other after the head of the nail has been formed. The nail is thereby thrown out with considerable force, and the lower jaws are thereby cleared for the reception of the next nail-blank.

Operation of the machina-Tl1e reel at the lower part of the machine is first wound with wire of proper thickness for the nails to be made. The end of the wire is then passed through the straightening-rollers and feeding mechanism, and between the knives, until the end of the wire projects somewhat above the latter. The machine is now set in motion. The movable cutting-knife and its sliding carriage are thereby moved by its actuating mechanism against the fixed cutting knife, whereby a piece of the wire is cut off having the shape shown in Fig. 12, so as to form a heavier head portion and a pointed shank portion. The movable cutting-knife presses at the same time the nail-blank against the fixed check in front of the fixed cutting-knife, so as to form the shank of the nail by forcing the reduced end for forming the point of the blank against the end of the check 0 and the side of the knife as shown. The carrier, having by this time been moved back by its actuating mechanism, grips the projecting head of the blank in its jaws, being then moved forward toward the jaws r 9" until the carryingjaws arrive at a point vertically above the same, when they are opened and deliver the shank of the nail between the jaws r g". The carrier moves bac toward the cutting-knives after the lower jaws close upon the shank of the nail, and hold the same rigid] for the action of the drop-die. This has been raised by its actuating mechanism (hiring the cutting off of the blank, but is now dropped as soon as its cam releases the lifting-piece of its cylinder, so as to impart thereby the required shape to the head of the blank, and thus finish the nail. The throwing-out lever is now quickly moved forward and the nail thrown out'ofthe machine. Simultaneously with the return of the carrier the movable cutting-kniic is carried cndwise or back, and the wire-feeding mechanism is operated, so as to expose the next adjoining part of wire to the action of the cutting-knives. The nail blank, when severed, is taken up by the carrier and transmitted forward to the die-jaws, where the head is formed by the drop-die, and then it is thrown out, and so on. Each complete rcvo lution of the driving-shaft will form, by the co-operation of the different actuating mechanisms, one complete nail, the head of which may be of any desired shape, either plain or fancy, according to the shape of thedrop-die. This machine may be applicable with equal carriage d, bracket-plate d straightening-roll ers d, retaining-cheek d, inclined dog d friction-roller d, lever (2 and serrated jaw (Z all arranged substantially as described.
